I just hope someone will soon be able to figure out the codes to install wikipedia into the Kindle, or even Sony/Cybook/Iliad.

The good side of it for Amazon is that they wouldn't need to pay 3G company per wikipedia page viewed per customer.
The good side for Kindle owners like me, is that I won't need to be in US to access Wikipedia.
The good side for Sony/Cybook/Iliad, is that they don't need to log into wireless to view wikipeida.
